Compact, lightweight sound level meter designed for the measurement of workplace noise levels to determine the degree of hearing protection that may be required. LED Alert screen provides a quick visual reference of sound levels. Rechargeable lithium polymer battery.
From the Manufacturer
3M™ Sound Detector SD-200 helps workers assess the need for hearing protection in noisy environments. A digital display shows the minimum, maximum and average decibel level (sound pressure levels) to help workers make informed decisions about hearing protection. Tri-color LED lights in green, yellow and red flash brightly when preset noise levels are reached, helping workers determine when hearing protection may need to be worn. Green LED flashes when noise measurements are between 80 and 85 dB. Yellow LED flashes when noise measurements are between 85 and 105 dB. Red LED flashes when noise measurements are above 105 dB. The device includes an averaging function that provides readings in highly variable environments, meaning the digital display of the decibel reading will not erratically jump around in environments where noise levels are highly variable. This function helps improve readability of the display.
Simple four-button navigation performs all functions, requiring little to no training for staff. This light and portable hand-held sound level meter comes ready to take measurements right out of the box with no configuration necessary. A lithium polymer battery provides up to 50 hours of use between charges. This rechargeable battery reduces the cost and disposal of replaceable batteries.
This detector is industry compliant, meeting applicable ANSI and IEC Class 2 standards. Specific standards include ANSI S1.4 1983 (R 2006), ANSI S1.43 1997 (r 2007), IEC 61672-1 (2002) and IEC 61010-1 (2010). The device delivers consistent performance with accurate, actionable readings.
Exposure to loud noises can adversely affect the ability to hear over time. Wearing proper hearing protection devices can help in reducing the harmful effects of noise. Sounds levels are expressed in decibels, often abbreviated as dB. Higher decibel numbers indicate louder sounds. Typical decibel levels associated with common sounds include: outdoors with no people or traffic 20 dB, normal conversation 60 dB, power lawn mower 90 dB, chain saw 110 dB, and 12-gauge shotgun 165 dB.
